I have had a Lowrance Elite 4x DSI since I bought my PA last July. It has performed really well and have had no issues whatsoever heading out 2 - 3 times a month, predominately in salt. Haven't treated her too nicely, has had a couple of dunks. A rinse of in fresh and good to go! The only concern I had was with an additional input port not being used that I didn't want salt in so covered it up with a big lump of plasticine. No issue!
